Nobody wants to give away their secret sauce recipe by explaining it in a patent that can be understood! That would be commercial suicide. Better to keep the secret and leave others to figure out how you did it.

So they patent mini tangential stuff in the most vague terms possible. I have yet to read a useful patent from the last decade. A 'this is how to make this thing' that somebody can use to make that thing. They're all just a pile of lawyer garbage at this point.

Yet another burden on business, yet another burden that can't be exported either.
